    So I have a 2009 Macbook Pro that ran out of space. I saw on You-Tube that you could clean up space and increase performance by deleting unused startup items. So of course, not knowing what I was doing, I deleted them.

    Now after my login, the computer goes to a blank screen. Nothing. Dead. What do sob?

    You can recover from a backup or reinstall Mac OS X.

    What OS X version are you on? If you are on Lion 10.7 or newer, you can just hold command-r when you boot and that will take you to a recovery screen. From there click reinstall OS X and the OS will download and install. You may be prompted for the AppleID you used to buy the OS.

    This will not erase your data.

    Thanks for that tip. I tried it and the same thing happened. Restarting gets me to my sign-in screen, but any user, including guest, simply goes to a blank screen.

    Do you know what OS X version you are on?

    Try a safe mode boot. That bypasses and startup/login items and may help.

    I think I'm Mountain Lion. I'll follow the link on "safe startup."

    Can you clarify... in your post above were you able to command-r into recovery then reinstall?
